DISHWASHING MACHINE.

.Applieation filed November 11, 1926. Serial No. 147,731.

The main object of this invention is to provide an improved dish-washingmachine which is highly efficient, the water being effectively anduniformly distributed to" the dishes.

A further object is to provide a dish-washing machine having theseadvantages which is of large capacity. a 1

Objects pertaining to details and economies of our invention willdefinitely appear from the detailed description to follow. The inventionis clearly defined and pointed outin the claims.

A structure whichis a preferred embodiment of our invention is clearlyillustrated m the accompanying drawing formlng a part I of thisapplication, in whlch:

Fig. 1 is a fragmentary view of a washing machine embodying the featuresof our 111- vention mainly in section on line 11 of Fig. 2.

Fig. 2 is a'plan view of the receptacle of the machine with theimpeller, dasher anddish supporting basket or rack removed.

Fi 3 is a plan view of our improved impeller and dasher.

F5 g. 4 is a detail section through the dasher blades on a linecorresponding to line 4-4 .of Fig. 3.

Referring-to the drawing, the receptacle 1 is provided with a bottomhaving a central recess or well 2 comprising segmental raised portions 3and depressed portions 4, these portions being disposed alternately asillus trated. The depressed portions form drain channels to the well andthe raised portions form baflles which prevent the water from setting upa rotary motion within the receptacle or break up such motion.

The impeller 5 is supported on the shaft 6 to rotate in this. well. Theimpeller comprises blades 7' radiating from the hub 7 and the upwardlyand outwardly inclined rim 8 on the blades.

Above the impeller is a dasher 9 having inclined blades rotating in aplane above and overhanging the inner ends of the raised portions of thebottom, the impeller elevating the water to this dasher and the dasherthrowing it upwardly within the receptacle. The dasher is mounted on theshaft 6.

The bottom of the receptacle has an opening 10 therein through which thebearing housing 11 of the shaft 6 projects. This bearing housing isprovided with a suitable packing and bearings, and also constitutes ahousing for the worm gear 12' on the lower end of the shaft. The bearinghousing is supported on a cross member 13 extending between the legs14;.

The motor 15 is mounted on a bracket 16 on the under side of thereceptacle. The receptacle cover 17 is removably secured to thereceptacle. I

A wire rack or basket 18 is provided for the dishes. This rack is madeup of a series of concentrically disposed receptacles of differentdepths and arranged. in stepped relation so that the water discharged bythe impeller and dasher is quite uniformly distributed to the dishes,that is, those in the inner receptacles do not obstruct those in theouter receptacles.

A drain cook 19 is provided disposed in one of the depressed portions,the bottom bemg inclined to this drain cock. An operatmg rod 20 isdisposed at the side of the receptacle.

Our improved dish-washing machine is, as stated, highly eflicient and isof large capacity.

Having thus described our invention what we claim as new and desire tosecure by Letters Patent is: v v i 1. In a dish-washing machine, thecombination of a receptacle provided with a bottom having a central welland segmentalshapcd radial channels communicating therewith, an impellercomprising radial. blades and an upwardly and-outwardly inclined rimmounted to rotate in said well, and a dasher having inclined bladesdisposed above the said impeller with the ends of the blade projectingbeyond the said central well.

2. In a dish-washing machine, thecombination of a receptacle providedwith a bottom having a central well and segmentshaped radial channelscommunicating therewith, and an' impeller comprising radial bladeshaving an upwardly and outwardly inclined rim at the outer ends mountedto rotate in said well.

' 3. In a dish washing machine, the combination of a receptacle providedwith a bottom having radially disposed alternately raised and depressedsegmental portions providing a series of drain channels, said raisedportions terminating at their inner edges in spaced relation providing acentral recess, an impeller comprising radial blades and an I n Jupwardly and outwardly incllned rim mounted to rotate in said recess,and a dasher above said impeller overhanging the inner ends of saidraised portions.

4;. In a dishwashing machine, the combination of a receptacle providedWith a bottom having radially disposed alternately raised and depressedsegmental portions providing a series of drain channels, said raisedspaced relation providing a central recess, and an impeller comprisingradial blades and an upwardly anchoutwardly inclined rim mounted torotate in said recess.

In witness whereof We have hereunto set 15 our hands. a
